That's her goal, and as far as I can tell she's been consistent and mostly successful in achieving it. I actually got to know her through her son, Todd. He and I struck up a casual conversation at a convention years ago (well, I can say decades ago, now) before I knew who his mother was, and we discovered we had common interests in piloting aircraft, the space program (I was working directly for NASA back then), and most SF. Todd and I have been friends ever since.Not real, but realistic. ;D
One thing led to another, and eventually my wife and I were invited to his mom's place in Ireland for a few days, I was tapped as one of the technical consultants on one of her Pern books, and eventually my wife, my kids, and I became "characters" in one of the modern Doona books (co-written with Jody Lynn Nye, another friend of ours). Believe me, it is a totally surreal experience to encounter characters named after yourself, living completely different lives in an alternate universe!
